After the battle began, the Great Heng Imperial Army was fighting in the way they do best, that is, annihilating the enemy with cannonballs!

They used a large number of super-heavy artillery and heavy artillery to carry out covered shelling of predetermined targets, as large as 300 mm shells, as small as 60 mm mortar shells, and the shells of the Great Heng people were thrown out as if they did not need money.

What, this time, in fact, the participating troops of the Great Heng Empire really don't have to worry about ammunition.

Because the Daheng Empire has been hoarding a large amount of ammunition every year for more than ten years after unification, many of which are early ammunition, but the quality is not good, and the storage period is not long enough, not to mention, and even because of great technological progress, now these old shells are not even scrapped, dismantled and recycled.

In recent years, the Daheng Empire has had a headache with the large amount of ammunition stored in the first few years after reunification, and it is not okay to throw it away, and it costs money to destroy it, and it is not necessary to give it away, so it often conducts live-fire exercises to shoot out old shells.

However, in the early years of the unification of the Daheng Empire, there were too many old artillery shells produced and reserved, if they really used all the live ammunition exercises, to be honest, even the wealthy Daheng Empire would have to feel heartache, not because of these old shells, but because of the wear and tear of the artillery!

I don't know how many barrels it will cost to shoot out the old shells in the Empire's stockpile.

But if it is used on the battlefield, then there are not so many concerns, the Daheng Empire is transporting all kinds of old ammunition here ship by boat, and now the artillerymen can fight openly, and even hit until the barrel is scrapped, it is estimated that there are still some shells left here!

This kind of large-scale artillery bombardment, that is the regular program of the Daheng Army, even the Olisa people on the opposite side have built strong anti-artillery holes early in the morning to prevent the fierce shelling of the Daheng people.

But they still didn't expect that the artillery of the Great Heng people would be so ruthless!

Even if there are many shells, this will even shoot out 300 mm shells!

And even knocked out the 150-mm heavy cannon deployed by the Orissa in the port area, and smashed several arms warehouses in the port area!

You know, there are Orissa 150mm heavy cannons in the port area, with an effective range of 12 kilometers, and they also have artillery observers on the front line, as soon as they observe the artillery unit of the Great Heng people trying to enter this area, they will immediately launch an artillery bombardment.

"How did they take down our port district?" Many of Orissa's soldiers have this doubt!

"Could it be that their navy also participated in the war, and the artillery bombardment was carried out directly from the Endless Strait, but no, their navy didn't come over, and our navy is still waiting in the Endless Strait, the batteries on the north and south sides are enough to block most of the shipping lanes of the Endless Strait, and there is also our fleet armed, it is impossible for their naval fleet to break in!"

Most of the Olissa's soldiers did not know that the artillery unit of the Great Heng did not come within their effective range of twelve kilometers, but stopped to build an artillery position about fourteen thousand kilometers away from the port area.

Because Dahengren brought over six 150 mm heavy cannons in service this time, just as the army's previous heavy cannons like to use naval gun technology, this 14-year-old 150 mm heavy cannon was also born from the navy's 150 mm naval guns.

This thing has a maximum effective range of 15,000 kilometers!

You must know that the 150 mm long-range suppression artillery of the armies of various countries is basically still about 12,000 kilometers, and the individual ones with excellent performance are only about 13,000 meters.

However, the army of the Great Heng Empire wants artillery with a longer range, so for the new cannon of 150 mm, the firing range is required to reach more than 15,000 meters.

With such long-range suppression artillery, the artillery of the Daheng Army can calmly carry out shelling from a safe position.

And in the process of shelling, it can also raise the high-altitude observation balloon unhurriedly to provide shooting elements for your own artillery.

Six new 150-millimeter heavy cannons, after bombarding the port area for a whole day, basically the port area was completely abandoned, and the many warehouses in the port area stockpiled a large amount of ammunition supplies, and as a result, they were blown away, and even the ammunition in the ammunition warehouse was detonated, causing an even more violent secondary explosion.

After the enemy's heavy artillery in the port area was eliminated, Daheng's other artillery with a relatively close range was also deployed close to it, directly blocking the Andan urban area north of the port area, and carrying out a fierce bombardment of the Andan urban area.

At this time, there are actually not many ordinary people in the city of Andan, and the civilians have already fled from the city in the past two months, because they have long known that a tragic war will break out here, and if they continue to stay in the city, it will be a dead word.

Although Zhou Qi, the king, leaned towards the Orissa, he was the king of the Dana people after all, and he couldn't watch more than 200,000 civilians die in the war.

After all, on both sides of the war, no one has any intention of caring about the life or death of the locals, whether it is the Daheng people or the Olisa, the cannonballs are all shot out like no money.

The Great Heng had a lot of ammunition that was close to expiration, and so did the Orissa.

In this Andan offensive and defensive battle, both sides can be regarded as having sufficient ammunition, which can turn the entire Andan City into ruins after the fight.

However, the current Orissa ammunition depot in the port area has been bombed, although it can still be supplied from the south through tradition, but the heavy artillery troops of the Daheng people are not easy to mess with, and the port area has been completely blocked, and the Orissa cargo ships want to transport the shells, they have to brave the artillery fire to approach and unload.

Under the cover of fierce artillery, Ye Weiming Zhongqing commanded the troops of the prince's army to advance towards the city again.

Although the soldiers of the prince's army were a little worse in terms of combat quality and weapons, Ye Weiming had already temporarily replenished them with a batch of heavy machine guns and mortars and a large number of grenades.

Under the cover of the heavy firepower and artillery fire of the Daheng people, they can still fight a dozen.

As for the 16th Division, it only sent reconnaissance battalions belonging to the division to disperse and participate in the battle on the scale of platoons, mainly for its own artillery units to guide the shelling targets, and the main infantry regiment did not go up.

Ye Weiming was unwilling to treat Dahengren's own troops as cannon fodder to fill the meat grinder of the war in Andan City.
